Abstract: The disclosed embodiments provide a system for predicting response rates. During operation, the system determines features representing historical applications to opportunities and historical responses to the historical applications by a poster of the opportunities, wherein the historical responses include interactions between the poster and candidates submitting the historical applications and notifications transmitted to the candidates of actions related to the historical applications by the poster. Next, the system applies one or more operations to the features to generate a predicted response rate of the poster to an application for an opportunity by a member of the online system. The system then compares the predicted response rate to a threshold to determine a recommendation related to the application by the member. Finally, the system outputs, to the member in a user interface of the online system, the recommendation in association with the opportunity.
